Definitions

  • the invention relates to a method and device for the identical skull and centric installation of jaw models in the most common articulator systems.
  • These devices simulate the jaw movement of the patient to be treated, whereby in addition to the mere opening and closing movement of the lower jaw about an axis of rotation, the two TMJ heads can also follow feed and sideways movements.
  • the articulator type determining which information content can be entered by the patient.
  • the extent of this information input also decides which information content the device returns or which information content can be used to determine a prosthetic work made therein.
  • the position of the upper jaw model in relation to the artificial jaw joints of the articulator is installed in a way that corresponds approximately to the patient's case.
  • this is made possible by a so-called face bow, which determines the position of the upper jaw in relation to the temporomandibular joints and to an arbitrary level, e.g. B. the hinge axis orbital plane.
  • B the hinge axis orbital plane.
  • additional reference values for this level such as the inclination of the articular path or the Bennett angle.
  • the lower jaw model is installed using a so-called centric registration, the patient preferably biting into a wax template after the lower jaw has been guided into the so-called central jaw joint position or the terminal hinge axis position with the help of the practitioner.
  • Different articulators differ in the overall height, the arrangement of the artificial jaw joints and the dimensions of the gypsum beams.
  • Articulators are comparable to computers in that, as described above, they provide information when they have previously been stored with information. In normal everyday routine, partially adjustable articulators are sufficient, in which some values, such as. B. the articular inclination or the so-called Bennett angle are fixed.
  • the height of the articulator determines the height of the plaster base after assigning the lower jaw model to the built-in upper jaw model.
  • the present invention is therefore based on the object of creating a method and device which make it possible to transmit a skull-related model installation, which was carried out with facebow A in articulator A, in any articulator B, without using the same patient with the corresponding one Facebow B to tap the situation again.
